Antec 1200OC @ 1600+ watt (4x GPU)

Team.AU · 24th November 2009, 11:42 AM

alright so i dont normally do psu testing or review and i dont have the equipment to do jonnyguru style testing but i can certainly test the unit works to pro specifications...

1. build two systems
2. power one system with antec 1200oc and the other independently
3. plug in four dual pcb gpus (2 GTX295, 1 MARS 295, 1 9800GX2)
4. load that ish up and check the power usage

the unit, antec 1200 oc

specifications

turbocache connectors (capacitor closer to power usage for powerspike)

fortified 24pin connector

the setup, p55 and x58 rigs

ALL GPUS powered by the antec 1200OC

LOADED UP, with ALL gpus loaded, and prime95 on the CPU

Powermetre shows the peak wattage to hit 1621, not bad for a 1200w psu

Air temperature is only 38 degrees with very low noise level

I think this PSU is strong enough to power any system I might want to run, next testing will come with CPU and 4x 5870 on LN2 and high voltage.

My goodness that's a lot of power lol. Would be a few hundred dollars a month if one were crazy enough to have that as their everyday rig??

Nice PSUs tho by the looks of it.

that power socket and atx load would annoy me so much.

Crikey, that's beautiful.

4 x 5870? Naw, go for 4 x 5970's

terrastrife · 24th November 2009, 11:53 AM

the problem is, 5870's are power efficient, i can make my gtx280 draw mroe than a hd4870x2 without too much problems

thats some serious power ....
LOL @ 1600W power peak ....

Impressive effort there.

Awesome.

Why do you use DVI-VGA adaptors? I'm sure those monitors have DVI input?

probably something to do with resolution/refresh rate

Nothing to do with the psu testing.. but I'm curious why you have the fans on the gpu's blowing into the gpu, not sucking air out from the gpu.. Seems like it should be the other way around? Air sucks in at the front of the card and blows out at the back, I know that's how all my folding cards are set up. Blowing air into them like that at the back of the card would hinder cooling?

terrastrife · 24th November 2009, 6:33 PM

look slike its positioned to supply air to the 'squashed' intake fan .

i put the fan on the bit that was hot, thats my cooling theory, cool the hot bits!

Makes perfect sense

That's fair enough, it's just that the way you've positioned that fan, it's trying to force air into where the fan in the card is trying to blow it out of. You'd get better results if you flipped the fan over.

If you want to get really carried away you can put a 80-90mm fan down the intake end blowing downwards and the 120 at the other sucking the hot air out. Just have to be careful the air doesn't end up looping around, ie sucking the hot air out and blowing it straight back into the gfx card intake.
